High Precision Structure Design
The application of custom-developed high precision aluminum alloy profile frame. 4+4mm curved laminated glass and 3+3mm plate laminated glass guarantees the structure strength and reliability.
Advanced Control System
PLC programmable controller and international advanced AC frequency conversion control technology improve the operating performance of Automatic Doors, enriches the functional design and extends the service life.
Static Brush Sealing System
The application of static balance theory makes better hermetic effect of automatic doors and anti-dust brushes.
Operating Mode Option
It provides 3 adjustable modes to realize lock, on-off operation and continuous operation. (on-off mode: when there is no one pass, it is in the static status. When people is detected to pass, it revolves automatically, which reduces power consumption.)
The Most Comprehensive Security Design
Vertical Anti-pinch Safety Switch/Horizontal Anti-collision Safety Switch:
Conductive rubber safety switch is very soft, which guarantees to activate the sensor with very small extrusion deformation to stop revolving door operating. Compared with photoelectricity and joint switch, it is safer and more reliable.
Anti-collision and Anti-pinch Force Sensitive Function:
When the automatic revolving wing meets the resistance which is over the set value (adjustable), the Automatic Door will stop operating.
Emergency Stop Function:
When the emergency occurs, just press down the emergency stop button, the revolving door will immediately stop operating.
Handicap Safety Function:

Anti-pinch Sensor (Optional):
It works when the revolving wing rotates to the point which is 700mm from the outer wall. When people or objects are detected in this distance, the system begins to work and the door stops operating.
Anti-collision Light curtain (Optional):
It adopts contactless anti-collision design. If people or objects present in the detective area, the revolving door will stop operating.
